The distributed system includes a system service, a first-type service located at an upper layer of the system service, and a second-type service located at an upper layer of the first-type service and having an interface display function. Both the first-type service and the second-type service are atomic services. A second device migrates a teaching video to a first device, and the first device plays the teaching video. A second-type service in the first device may call a first-type service in another device, to control the another device to capture a user action picture video, process the teaching video and the user action picture video to obtain teaching guidance, and play the teaching guidance.
